Check Digit Verification of cas no

The CAS Registry Mumber 70119-97-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,0,1,1 and 9 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 70119-97:
(7*7)+(6*0)+(5*1)+(4*1)+(3*9)+(2*9)+(1*7)=110
110 % 10 = 0
So 70119-97-0 is a valid CAS Registry Number.

A Cannabinoid Derived Prototypical Analgesic

Melvin, Lawrence S.,Johnson, M. Ross,Harbert, Charles A.,Milne, George M.,Weissman, Albert

, p. 67 - 71 (2007/10/02)

The synthesis and analgesic testing of 3-cyclohexanol (1) are described.Prior (SAR) studies led us to conclude that the pyran ring of 9-nor-9β-hydroxyhexahydrocannabinol (HHC) was not necessary for the expression of biological activity in this series of cannabinoids.Analysis of models and the use of molecular mechanics calculations suggested that a simpler compound, such as 1, would possess the biological activity of HHC.Compound 1 was prepared in nine steps from acetonitrile (2).Biological testing in five models of pain shows that compound 1 and morphine are equally potent as analgesics and demonstrates that the pyran ring of HHC is not necessary for biological activity.Further simplification of 1 was pursued by the synthesis of 4--2-pentanol (17), but this derivative exhibits significantly reduced analgesic activity.
